I have a Weil-McLain boiler supplying the hot water to my cast-iron radiator heating system. Any one have a thought on what the pressure and temperature gauges should be reading? The temp gauge goes to 130-140F after the boiler cycles off, and the pressure gauge appears to be fairly steady at +/-20 lbs. Should the pump that circulates the hot water be running when the furnace is no longer burning?
Thanks!
Thanks!
